Not at all. The success rate of a root canal is about 85%, which means in most cases a root canal last for a lifetime. There are circumstances where a tooth with a root canal becomes infected again which might cause pain to the patient. In that situation the root canal can be retreated.
What is a retreatment? It’s a procedure of redoing the root canal by re-cleaning the inside of the roots, disinfecting and obturating each canal. Some teeth may require an apectomy instead, which is a microsurgery used to remove the infected tip of the root. Modern techniques of restatements and apectomy work well.
In rare cases where a tooth is fractured all the way to the root, extraction is the only thing that can be done. A dental implant, a bridge or a partial can later replace the tooth.
